The backtrace looks like nonsense, unfortunately, e.g., it shows two 
arguments to adjust_decode_mode_spec_buffer, a function that has just 
one argument, and it shows xrealloc being called with 
size=18446744073709551597, even though the code passed 
FRAME_MESSAGE_BUF_SIZE (f) + 1 as the size, and I don't see any way to 
get 18446744073709551597 even if overflow is taken into account.

Can you reproduce the problem?

Can you compile with '-g3 -O0' and reproduce the problem?

I can reproduce if I link against gtk3. Not on gtk2/1

Thanks; please send a recipe for reproducing it, starting with 'emacs 
-Q'.  It'd be nice if you could rebuild with -g3 -O0 first and send a 
backtrace.

I can reproduce with my config on Spectrwm tiling WM.
However under KDE it runs fine without segfaults.
Also "emacs -Q" would hang but not crash as it did.
Must be an issue with gtk3 and the Spectrwm wm.

I've attached the Crash output as well as the configure/etc.

I see in the output from the crash:

> (emacs:19316): Gtk-CRITICAL **: gtk_distribute_natural_allocation: assertion 'extra_space >= 0' failed
> Fatal error 11: Segmentation fault

In the etc/PROBLEMS file, we have the following item regarding a crash
with the same error message:

> *** Emacs built with GTK+ toolkit can unexpectedly widen frames

Perhaps this should therefore be merged with the bugs mentioned there:

Sounds good to me; I merged them.
